Chemical Equilibrium Lab Report Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions. Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change. This lab consists of two

this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ can be the same or different; at equilibrium‚ the concentrations of both reactants and products are constant. In this experiment set up‚ the reaction between ethanoic acid and ethanol to produce ethyl ethanoate and water is a reversible reaction as shown by the following equation: CH₃COOH + CH₃CH₂OH↔CH₃COOCH₂CH₃ +H₂O The Equilibrium Law states that

Na2C2O4 in water at different temperatures‚ determine the effect of temperature in solubility‚ and to apply Le Chatelier’s Principle. We can do all this by simply titrating a certain amount of standard KMnO4‚ and measuring how much KMnO4 was needed to help Na2C2O4 reach chemical equilibrium at certain temperatures. In doing this‚ we will have fulfilled all the goals of our experiment‚ as well as being able to determine the Solubility of Na2C2O3 at both 20 and 100 C‚ in addition to determining both experimental

In the story “Raymond’s run”‚ the character goes from being self centered to helping her brother and be willing to help other people. In the beginning of the story squeaky is a girl‚ who is a very fast runner‚ but she is also self centered. At the end of the short story she is less self centered and Offers to help train her little brother. She also discovers winning isn’t everything and she should help others In the beginning squeaky explains that she helps out her little brother because he is special

Chemical equilibrium is a state of balance within a system of chemical reactions. Equilibrium in chemistry is achieved when substances are produced and broken down at the same rate and thus‚ the number of molecules of each substances becomes constant. Thermodynamics is a branch of physical science that involves the relationship between heat and other forms of energy (Energy‚ Enthalpy‚ and the First Law of Thermodynamics). There is a more specific area of thermodynamics that explicitly pertains to

Government-Run welfare The current use of government-run welfare systems is an ineffective and inefficient way to help solve poverty and unemployment in urban areas. Flawed in almost every way‚ it requires immediate improvement and attention‚ and could be improved with privatization of many welfare programs‚ including prisons‚ charity and housing. Welfare can be improved in more ways than one‚ and one of the biggest problems in need of a fix is the government’s attitude toward the programs they

Inspired by Run Sausage Run! “Alright boys‚ at 11:00 p.m. sharp we bust out it will be a difficult escape and not all of us might make it out alive.” I informed my crew‚ it will be difficult but I think we can do it. Private Hotdogger comes up behind me and whispers‚ “ Get ready General‚ the workers all leaving and locking up.” I sprint as fast as I can all the way down the counter‚ I grab medical stuff gear and a mic for everyone to communicate. After two minutes everyone’s ready for the run‚ I see

profit as much in the short-run as they would in the long-run. Why might a firm choose to do this? Give an example of this in Vietnam. (100 words) Competitiveness is the core key for every business firm to remain in a particular market segment. There are too many rivals in the market‚ although the demand is still high. Price should be in the best and the firm with short-run oriented planning and implementation cannot afford the high marginal costs for its products‚ since the price of inputs is also

Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and the maximum force

surprise: investment is not the key to growth (by Easterly) * Investment cannot be the source of growth in the long run * The belief of increasing buildings and machinery is the fundamental determinant of growth = capital fundamentalism * Investment increases machine per worker would lead to diminish return in long run * Technological progress is the key to growth in long run because it increases the productivity of the machine itself rather than machine per worker * Labor-saving technology
